The 1-1/2 in. Male NPT Schedule 80 PVC Plug is a Schedule 80 (gray, heavy-duty pressure) PVC Male NPT threaded plug for use in water treatment, chemical dosing, irrigation, pool, and industrial piping systems where corrosion resistance and chemical compatibility are required. PVC's inert chemistry makes it compatible with chlorine, sodium hypochlorite, dilute acids, caustic solutions, and most water treatment chemicals that attack brass or steel fittings.
